One of the rare genetic diseases with sensory hearing loss is the microdeletion 7q syndrome. First described in the 1990s, only 7 cases of patients with this disease are described in the literature. Although this mutation is not well known, otological treatment is necessary if the DFNA5 gene is affected. A mutation in this gene leads to progressive hearing loss. Affected children therefore need regular evaluation of their hearing to ensure adequate treatment with hearing aids at early stages. We now present a case of an affected child with sensory hearing loss, mental retardation and anogenital malformations...

BACKGROUND: A cochlear implant (CI) is an electronic prosthesis that can partially restore speech perception capabilities. Optimum information transfer from the cochlea to the central auditory system requires a proper functioning auditory nerve (AN) that is electrically stimulated by the device. In deafness, the lack of neurotrophic support, normally provided by the sensory cells of the inner ear, however, leads to gradual degeneration of auditory neurons with undesirable consequences for CI performance...

OBJECTIVE: The present study attempted to evaluate hearing handicap in adults with auditory neuropathy spectrum disorder (ANSD). The study also attempted to determine if gender, pure tone average, speech identification scores (SIS), and reported duration of hearing loss could predict the hearing handicap in adults with ANSD. MATERIALS AND METHODS: Hearing Handicap Inventory for Adults and Hearing Handicap Questionnaire were administered to 50 adults with ANSD. RESULTS: Using both the scales, there was a significant hearing handicap in both the social and emotional domains in adults with ANSD...

: The cochlear implant, the first device to restore a human sense, is an electronic substitute for lost mechanosensory hair cells. It has been successful at providing hearing to people with severe to profound hearing loss and as of 2012, an estimated 324,000 patients worldwide have received cochlear implants. Users of cochlear implants however, suffer from difficulties in processing complex sounds such as music and in discriminating sounds in noisy environments. Recent advances in regenerative biology and medicine are opening new avenues for enhancing the efficacy of cochlear implants by improving the neural interface in the future and offer the possibility of an entirely biological solution for hearing loss in the long term...

BACKGROUND AND OBJECTIVES: Patients with SCL26A4 mutations presenting with Mondini deformity and enlarged vestibular aqueduct (EVA) tend to have comparable residual hearing. Although cochlear implantation (CI) produces good results in this group, deterioration of residual hearing can be an adverse event after surgery due to accompanying cochlear malformation and perilymph leakage during cochleostomy. The purpose of this study was to investigate if CI in patients with SCL26A4 mutations via the round window (RW) approach could achieve preservation of residual hearing, and to evaluate their speech reception with electroacoustic stimulation (EAS)...

OBJECTIVE: CHARGE syndrome is associated with a variety of temporal bone anomalies and deafness. The lack of surgical landmarks and facial nerve irregularities make cochlear implantation in this population a challenging endeavor. This study aims to describe a safe and efficacious transcanal approach for cochlear implantation that obviates the need to perform a mastoidectomy and facial recess. PATIENTS: Three children with profound hearing loss secondary to CHARGE syndrome...

BACKGROUND: Most children with hearing loss who receive cochlear implants (CI) learn spoken language, and parents must choose early on whether to use sign language to accompany speech at home. We address whether parents' use of sign language before and after CI positively influences auditory-only speech recognition, speech intelligibility, spoken language, and reading outcomes. METHODS: Three groups of children with CIs from a nationwide database who differed in the duration of early sign language exposure provided in their homes were compared in their progress through elementary grades...
